WP Super Cache First page load doesn´t work in iPhone – I need to reload to make it work (1 post)

Is there somthing I´ve done wrong in the settings? I have to reload every page once to make it display in my iPhone. First time I get the message: "Safari can´t open the page. Error: can´t load raw data"

It works in my desktop web browser. But if I run tools.pingdom.com the issue occationally appears there as well.
